Color Description
In large oil paint lines, there are often two shades of Cobalt Blue, sometimes named Cobalt Blue and Cobalt Blue Deep. Whereas Cobalt Blue is generally based on the pigment PB28 (cobalt aluminium oxide), Cobalt Blue Deep is often based on PB72 (cobalt zinc aluminate). Sennelier Oils contain a single Cobalt Blue, based on pigment PB72, equivalent to Cobalt Blue Deep in many other brands.
